caj kills IOC #1938

Open berryma4 opened 7 years ago

berryma4 commented 7 years ago

I've had two cases in which someone was restarting their IOC a few times, then the IOC gets bogged down with invalid request:

CAS: forcing disconnect from 192.168.xxx.xxx:42365
CAS: request from 192.168.xxx.xxx:42367 => "bad resource ID"
CAS: Request from 192.168.xxx.xxx:42367 => cmmd=2 cid=0x11 type=20 count=1 postsize=0
CAS: Request from 192.168.xxx.xxx:42367 => available=0x3c974 N=0 paddr=0x36fbe08
CAS: forcing disconnect from 192.168.xxx.xxx:42367
CAS: forcing disconnect from 192.168.xxx.xxx:42370

This sounds like our previous issue, but showing itself in a different way. https://github.com/ControlSystemStudio/cs-studio/issues/1174

Is this with BOY where you could try both pvmanager and vtype_pv? Maybe even another CAJ-based client (well, not sure which one), so we see if this is in CAJ or the result of using CAJ in a certain way.

I will try to reproduce with both.
